Breification B21: Does Using a Power Bank Damage Your Cell Phone’s Battery?

The direct answer to the above question is this: there is no scientific backing to the idea that the use of a portable charger, AKA a power bank, leads to faster deterioration in the battery life of your smartphone or any kind of device for that matter.

A power bank that is properly designed and built to high-quality standards poses no harm to your smartphone, music player, or tablet. Absolutely none. Also, note that you need to use a power bank with a power rating that matches your phone’s. Using a power bank that discharges a higher voltage than what your phone is built to handle is a dangerous thing and can damage your phone's battery.

In the same way, a poor-quality power bank can damage your cell phone battery and cause it to degrade faster than usual. A portable charger of questionable quality can potentially deliver a lower or higher voltage than your smartphone is designed to handle, and this can damage not only your phone’s battery but possibly other electrical circuits in it. 

If you see someone complain that a power bank damaged their phone, chances are that they charged said phone with an inferior quality or faulty power bank. Using a power bank in itself does not damage your cellphone battery in any way.

It is simple logic:

If your smartphone is worth anything to you, you should be using good quality accessories with it, especially when it comes to power and battery charging accessories. Also, note that using a damaged portable battery can result in problems for your phone. If your power bank begins to bulge, that is an indication that it has a swollen battery. Danger. Stop using that portable battery to avoid damage to your phone and your person. You don’t want a fire outbreak on your hands.

Does using a power bank damage your phone battery?

In conclusion, what will damage your phone battery are substandard power banks. So what should you do? Avoid buying ridiculously cheap, nameless and faceless portable chargers, especially if you own a good-quality smartphone.

What other things may damage your cell phone battery?

As a bonus point, here are a few more things that can damage your phone battery. Using or charging your phone in extreme temperatures is bad for the battery. More advanced phones will cut off the charging process if the environment gets too hot or cold.

So can Power Banks Damage your Mobile Battery?

Most mobile phones need a power bank or wall charger that provides an output voltage of about 5V. The issue, however, is that there are many power banks that are of questionable quality. These power banks can distribute a lower or higher voltage than what is required to charge your cell phone. Using the wrong voltage to charge your mobile phone can cause serious damage to the battery life of your mobile device.

Does that mean High-Quality Power Banks will not damage my Mobile Battery Life?

Yes, if you purchase a high-quality power bank from a reputable manufacturer and you have an appropriate charging cable, you can rest assured that your mobile battery life is safe. It is crucial to check the output voltage of the power bank in relation to that of your phone. When the output voltage matches, there cannot be an issue with the battery life of your mobile device.

Power banks can damage your Mobile Battery


With the way many people use their mobile phones these days, it is becoming very crucial to keep the mobile battery charged very often. It is a fact that a high percentage of mobile phone owners need to charge their phones at least once a day. Of course, the perfect solution to charging the mobile phone will be to stay glued to a wall outlet to continue charging the phone.

So what causes Low Battery Performance?

Generally, a regular lithium battery will have a minimum of 500 full charges in its life cycle. This means that if you charge your phone for 18 months, your phone battery would have exceeded the 500 full charge cycles. By this time, the performance of the mobile battery will be noticeably worse. If you use a mobile device that has a replaceable battery, you might change the battery at this stage.

Conclusion

Lastly, when buying a power bank for use with your devices, be sure to check the power ratings to confirm that it discharges voltage and power that is specified for your phone. This is important. Those items are usually of substandard quality and are more likely to damage your cell phone battery.
